Near

Unified API + Near Integration Workflow

In the following guide, the integration process for the near chain is covered. The Near integration aligns with the general Unified API process but with network-specific parameters.

Get an authentication token to start using the Unified API.

Request examples are provided using cURL.

To check the integration guides for other chains, refer to the Networks section.

Key Near-specific details

  • chain — always set to near for Near-related requests.
  • network — environment in which the transaction is processed (mainnet only).
  • stakerAddress — account address initiating staking, unstaking or withdrawal transactions.
  • amount — amount of tokens in NEAR.

Staking Flow

1. Create Staking Request

Send a POST request to /api/v1/unified/staking/stake.

Example request (for mainnet network):

curl --request POST \
     --url https://api-test.p2p.org/api/v1/unified/staking/stake \
     --header 'Content-Type: application/json' \
     --header 'Authorization: Bearer <token>' \
     --data '{
    "chain": "near",
    "network": "mainnet",
    "stakerAddress": "c9cd49da4fb3cade542d625fa909ac443e77a1cb10e0287df6c5b8df7e4cc040",
    "amount": "1"
}'
  • chain — blockchain network, always set to near for Near-related requests.
  • network — environment in which the transaction is processed (mainnet only).
  • stakerAddress — Near implicit account address.
  • amount — amount of tokens to stake, minimum amount is 1.

Example response:
